Not very clearly worded as I think I might lack the vocabulary to describe the parts. Hopefully you can see what I'm on about.

Where there is no metal encasing / shrouding the rotor, is that because there is a part missing? Or are they due to IWC modifying the design and either version is correct and complete?

Any advice very gratefully received
I think the design was modified - the ones with the wider ring/shroud seem to be earlier. In the later ones, an equivalent part is still there, it's just that it's much narrower and doesn't overlap the rotor.

I think (although I'm not certain about this) the later ones might also have a thicker rim on the inside of the caseback that maybe performs the same anti-magnetic sheilding function.

Incidentally - if you are removing or installing the little rubber bumpers that lie between that outer movement ring and the case, you do it by sliding them around until they are in line with the gap in the ring near the balance wheel and take them out that way,

If you look at those two images one is a Cal 8541 and it looks like the other is Cal 8541B, which I believe came later.

Yeah, that would make sense if they changed the ring design when they went from Cal 8541 to 8541B. But these rings are specific to the Yacht Club.

Interestingly, my YC 8514 and 8541Bs both hack (hacking is one of the features that is supposed to separate these calibres by some accounts).

Thank you for responding so quickly. I foolishly discounted some otherwise nice YCs with the 8541b, thinking they were missing the anti-magnetic ring / shield.
Lots to learn with vintage!

Lovley!

That green "marble" dial YC is very rare. I've seen one or two (possibly the same one?) for sale on ebay and Chrono24 for exorbitant sums.. I think there was also a blue "marble" version?

I'd be very interested to know what the dial looks like really close up and what it is actually made of / how it is finished.

There are two versions, one blue and one green. The dial looks like a dial surface with blue or green paint

I was under the impression that these were stone dials, is this not the case?

It would seem a bit tacky if they are painted rather than real stone, given that other brands (notably Rolex) were doing various stone dials at this time.

It's not possible to say from these photos though. Really needs a macro lens (preferably manual focus as autofocus will target the crystal and deoth of field is very shallow), or a microscope with camera attachment.

Hello all. The Yacht Club is often compared to the Rolex Datejust of the same era (1600, 1601, 1603). The dimensions appear to be nearly identical and the proportions are very similar. Yet, I can't find a single picture online of a Datejust next to a Yacht Club.

Does anyone here have both, and if so would you be willing to share a pic (or several)?

Cool watches! I never really looked into them until now.

Please can I ask... Shopping for vintage yacht clubs, I'm seeing some movement shots like this:


And others like this:


Where there is no metal encasing / shrouding the rotor, is that because there is a part missing? Or are they due to IWC modifying the design and either version is correct and complete?

Hi.
I've had three IWC 811 and two of them don't have the "outer ring" (as in your second photo), while one has it (like first photo).
The one with the "ring" has serial numbers 1.882.xxx for the movement (i.e. 1967) and 1.883.xxx for the case (1968-1971); the two without the "ring" have serial numbers 1.960.xxx (movement, 1969) and 1.930.xxx (case, 1969-72) and 1.974.xxx (movement, 1970) and 1.964.xxx (case, 1970-73).
The first one has movement 8541 (1967) the two other 8541B (1969 and 1970).
Therefore, maybe the presence of the "ring" depends on the movement (8541 or 8541B); in any case, the shift has happened around 1969.

Edit: in the first sentence I made a correction

Therefore, maybe the presence of the "ring" depends on the movement (8541 or 8541B); in any case, the shift has happened around 1969.

I think it just changed around 1969 as you say. Both my YCs have the 8541B but the earlier one (1968) has the wider ring and the later one (1971) doesn't.

If you try to take the watch apart the reason for the change is obvious. It's pretty much impossible to remove the rotor on the movements with the wider ring without first taking the movement out of the case. That wouldn't be a big deal, except that taking the movement from the case is quite fiddly because you need to remove the rubber bumpers first. With the narrower ring you can remove the rotor and get access to the movement on the non-dial side without removing it from the case.

Hi.
As far as bracelets are concerned, there were three references: ref. 10 (Oyster), ref. 11 (beads of rice) and ref. 13 (double grain).
Refs. 11 and 13 were made by Gay Freres, bearing their engraving on the clasp.
Ref. 10, on the contrary, on the clasp has a marking representing a sort of sun.
Whose mark is it? Who was the producer?
Thank you for satisfying my curiosity.

I see you've found the Omega Buckles thread I was about to direct you to!

I too would like to know more about the "MG" factory (whose trademark seems to be that sun logo). There is so much that just isn't documented online about historical Swiss brands, especially the many who just made cases, dials, bracelets, etc. for the more famous watch brands.

For cases especially, it's very unclear how many case styles of the 1950s - 1970s were designed by watch brands (and maybe then manufactured by other companies), and how many were both designed and manufactured by 3rd party companies.
